Charybdis

The infamous "Ruler of the Skies", Charybdis, is a Calamity-class flying monster affiliated to the "Dragon" species as he was born from Veldora's magicules and humanity's violence and malice. Its raw strength is akin to that of a Demon Lord, but its incapacity of rational thought got it ranked down to Calamity rather than Disaster class.

Spawning
To spawn Charybdis, one has to find a Charybdis cave first. It is a very rare structure, filled with the skulls of those ones who were brave enough to enter it. In the middle of the cave, one will find the Charybdis core. In the ancient lore, it is said that by sacrificing a living creature by merging it with the Core, a horrifying monster will appear, with a wish to destroy the World and all of its residents.


 * In other words, you can get any 'Intelligent Life Forms' mobs (Human-like mobs like Villagers, Pillagers, Otherworlders + Humanoid Mobs like Goblin, Orc, Lizardman,...) to step on the Core, or just right-click them with the Core in your hand.
 * If the player has Unique Skill Investigator, they can use  command. The command will then tell the player if there is a Charybdis Cave within 500 blocks from them.
 * With the help of Degenerate skill, you can just right-click the core on the ground, this will have a chance to help you 'fuse' with the core and get the skills, but it can take away your magicules, as well as prove fatal.
 * Keep in mind that it isn't certain you will obtain all of those, as they have their chances too. The higher your Analyst level is, the higher the chance you get.

Drops
Active Charybdis Core - when right-clicking the core, it will bestow some skills (Gravity Manipulation, Magic Sense, Ultraspeed Regeneration, Magic Jamming) and between 10k-200k Magicules upon the Player.

Behavior
Charybdis is a large hostile mob. It will attack the player whenever it will notice them. Charybdis will also be always flying and destroying blocks in its path.

Immunity
As the Ruler of the Skies, Charybdis is immune to Drowning, Fall, Cactus, Arrows, and Suffocating damage, as it can easily destroy any block in its path.

Skills and Magic Moves

 * Tempest Scale: Charybdis will drop its scales off from time to time. The scale will then start flying towards the player for a good amount of time. The scale is pretty much unavoidable and it will deal good damage upon contact with a player.
 * The scale can be killed and will drop the "Tempest Scale" item on death.
 * Gravity Manipulation: As a being from the "dragon" species, Charybdis, like any other dragon, possesses the ability to fly, and will be constantly using it.
 * Ultraspeed Regeneration: With the help of this skill, Charybdis will be able to regenerate its health points at high speed.
 * Magic Jamming: Thanks to its scale and this skill, the Ruler of the Skies is immune to every Vanilla Status Effect [except Poison].
